Abstract (en)
[origin: WO2022179948A1] The invention is directed to a fall-classification device (100) with a receiver unit (102) configured to receive wireless communication signals (W) from wireless transmitters (101, 103) and a subject-activity data determination unit (106) configured to determine and provide, using signal-quality values determined by a quality signal determination unit, respective subject-activity data indicative of at least two subject-activity metrics of a subject (S) within a sensing volume (V1). A fall-event detection unit (108) is configured to determine, based on a time variation of the subject-activity data of at least one subject-activity metric, whether a fall-event has occurred. A fall-event type classification unit (110) is configured, using a predetermined algorithm and subject-activity data of at least two subject-activity metrics determined during a first time span before and a second time span after the determination of the fall-event, to determine a fall type, from a predetermined list of fall types, with increased accuracy.
